Analysis of underground garage roof slab no-return roof structure in the construction phase travel route area

Abstract

This paper adopts the calculation method of finite element combined with manual analysis to analyze the structural deformation of the underground garage roof slab without back roofing in the construction stage of the traffic route part, and proposes the structural slab reinforcement method combined with the actual construction situation, which shortens the construction period and reduces the cost compared with the traditional full scaffolding back roofing method and has a strong promotion, which can provide the theoretical reference basis for the subsequent works.
